On a standard Monopoly board, which square is diagonally opposite 'Go'?

On a standard Monopoly board, the square diagonally opposite to "Go" is "Free Parking." In the classic Monopoly game layout, "Go" is located at one corner of the board, and "Free Parking" is situated at the opposite corner diagonally. Players move around the board in a clockwise direction, passing "Go" as they proceed. "Free Parking" is known for being a space where various house rules are sometimes applied, such as collecting money placed in the center of the board throughout the game.
